Question

Identify the axis of symmetry for the graph of g(x) = 5(x - 2)^2 + 4

Answer 1

I tried it multiple times, at first I got -2, then I thought about it more and got 20, then finally I switched to using PEMDAS and got 100 and none were right so far... HELP?!?!

Answer 2

y=a(x-b)^2 +c

x=b is the axis of symmetry

Answer 3

like this
y=2(x-3)^2 +11
x=3 is it (axis of symmetry)
now can you go on ?

Answer 4

so no negitive sign goes into the axis of symmetry?

Answer 5

OH! IT WORKED WITH POSITIVE 2!!!!!

Answer 6

if you write the equation in standard form like that y=a(x-b)^2 +c
the zero of (x-b)^2 is axis of symmetry
so (x-2)^2=0
then (x-2)=0
then x=2

Answer 7

So, in:

y=a(x-b)^2 +c

x=b is the axis of symmetry


equasion, can you break down what each mean? My lessons are a joke and yet they expect me to learn all this!

Answer 8

How do I graph like that? That could come in handy!!!
